The study investigates contextual effects on the processing of pre-verbal (preVf) and postverbal (postVf) focus sentences in an eye-tracking experiment. For comparison, lexically marked focus (only-f) sentences were also included. The test sentences were presented following two types of linguistic context: restrictive or non-restrictive. It was hypothesized that if preVf exhaustivity is purely structurally encoded, gaze will converge on the exhaustive target image at a similar rate in the two contexts, just as it does in the case of only-f. However, if context also has an effect on the emergence of exhaustivity in preVf, gaze should converge more slowly on the exhaustive target in the non-restrictive context than in the restrictive context as predicted in postVf. The results support the latter prediction: fixation patterns diverge in the case of both preVf and postVf sentences, while they do not in the case of the baseline only-f.

语言穷举性推断取决于上下文

该研究在眼动追踪实验中研究了语境对前言（preVf）和后言（postVf）焦点句处理的影响。为了进行比较，还包括了词汇标记的焦点（仅-f）句子。测试句子是根据两种语言环境呈现的：限制性或非限制性。假设如果preVf穷举性是纯结构编码的，则凝视将在两种情况下以相似的速率收敛到穷尽目标图像上，就像只有-f一样。但是，如果上下文也影响preVf中穷举性的出现，则注视在非限制性上下文中的收敛应比在postVf中预测的限制性上下文中的收敛慢。结果支持后一种预测：
